I have all nessesary stuff antenna mount and coax its hooked up but getting horrible transmission like. I'm not in range I live a mile from I 40. And candy recieve any truckers accept faintly I've gone through 2 antennas so idk

 

Did you tune the antennas? Also how are your grounds?

 

What kind of antenna mount are you using? You wouldn't believe how many times I've seen people get the mounts that use the 3 piece stud mount assembly with the white plastic washer in the wrong place. The white washer needs to be on top of the surface, not below it. It is a spacer that keeps the transmitting part of the antenna from connecting to the bracket(or body), the grounded portion of the antenna mount.

Does your radio have a built in SWR meter? If not, do you have an external SWR meter?

 

Its a mirror mount with 4 bolts but I put it on the bed of my truck I have a Trc499 and a oil coil 4 foot whip

 

Sounds like you just need to hook a swr meter to it and adjust your antenna height.

ive adjusted it a hair at a time n it seems to get better the higher I go then I run out of antenna lol

 

What is the best match you can get?

 

Best is a 1:1

 

anything below 1.5 is good 1.1 is very good i got a littler over 1.2 and adjusted modulatio setting inside radio search it on google its pretty easy to do...

 

I wouldn't suggest to anyone to open up their cb radio and start tinkering with things, with or without an instructional video.

But you def need to get an swr meter and tune your antenna. You also need to check and clean all...ALL your grounding points in the jeep. Its also VERY important that your antenna bracket (NOT THE ANTENNA) is grounded well. Once all of this is said and done come back and let us know if there are any other problems.

 

also you need to have at least 1/3 of your antenna above the roof line.

 

agreed common sense should come into play..

 

at least ive just got a k30 on rioof at rear good enoughf for me picked up bran new cobra 29 classic with built in swr 69.00 of ebay
